Quick Answer: Xumo, LLC is an American internet television and consumer electronics company. It is a joint venture of Charter Communications and Comcast that operates the free ad-supported streaming television and advertising video on demand service Xumo Play. It develops digital media players and smart TVs. The Xumo Play platform's service operations are based in the Orange County suburb of Irvine, California. As of October 2020, Xumo Play has 24 million monthly active users. It was initially a joint venture between Viant Technology and Panasonic; Time Inc. later acquired Viant's stake, and the service as a whole was acquired by Comcast in 2020, seeking to use it as a complement to its paid streaming service Peacock. In 2022, Comcast announced that Xumo would become a joint venture with Charter; under the venture, Comcast also contributed its digital media player and smart TV businesses—which are based on Xfinity's X1 software platform—to the company under the Xumo Stream Box and Xumo TV brands.
